## [1.0.0] - 2026-05-20

### Added

#### Project Foundation
- Kotlin Multiplatform project setup targeting Android and iOS with Compose Multiplatform

- Compile SDK / target SDK 37, minimum SDK 24
- Version catalog at `gradle/libs.versions.toml`
- Dynamic version name generation: `baseVersion + git hash + buildDate`

#### Calendar Core Views
- **Month View**: 6x7 day grid with dynamic row count (4/5/6 weeks) based on actual month shape
- **Week View**: Single-week horizontal pager activated by collapsing the month view
- **Year View**: 4x3 mini-month grid with swipe-based year navigation and Hero Zoom transition
- **Infinite Paging**: `Int.MAX_VALUE` virtual pages centered at `Int.MAX_VALUE / 2`, enabling boundless month/week/year navigation
- ISO 8601 week numbering with Monday as the first day of the week
- Today indicator with border outline; selected-today state uses `primaryContainer` for softer visual treatment
- Non-current-month days are grayed out for visual clarity
- Auto-select today (if within range) or first day / Monday on page changes
- Click month header to jump back to today
- Cross-month week selection: intelligently selects the appropriate date based on swipe direction

#### Collapse / Expand Animation
- Drag-driven month-to-week collapse gesture on the calendar grid
- Spring-based snap animation that auto-settles to the nearest state on release
- Two-phase whole-block slide-up collapse animation with fade-out for non-selected rows
- Dynamic drag range computed from actual visual height change for 1:1 finger tracking
- Fling velocity threshold (800 dp/s) for quick swipe snap
- Collapse threshold set to 8% for easy fold/unfold triggering
- Pull-down gesture to expand from collapsed week view back to month view
- Week pager cross-fade transition to eliminate blank gaps during page switches

#### Chinese Calendar (Lunar)
- Lunar date display below each day number (using `tyme4kt`), showing month name on the first day of each lunar month
- Twenty-four solar terms (节气) annotations
- Traditional lunar festivals (春节, 端午, 中秋, etc.)
- Western solar festivals
- Legal holiday and compensatory workday badges (休/班) in the top-right corner
- Priority-based annotation display: legal holidays > lunar festivals > solar terms > solar festivals > lunar day

#### Personal Shift Scheduling
- `ShiftPattern` data model with anchor date + cyclic sequence for periodic work/rest schedules
- Independent from public holidays
- Work/Rest capsule badge display on DayCell
- Configurable legal holiday overlay toggle (default off)

- Precomputed dp-to-px conversions and TextLayoutResult caches
- Pager cache optimized (`beyondViewportPageCount = 0`)

#### Build & Testing
- R8 code shrinking and resource optimization with ProGuard rules
- ABI filtering (`arm64-v8a`, `armeabi-v7a`)
- App Bundle language/density/ABI splits
- Unit tests for `CalendarViewModel`, `CalendarUtils`, and `ShiftPattern`
